Very Unique and Strange Computer RAM/ CPU? Problem

I recently built a new computer, and after building, I found both RAM sticks were found in the BIOS (It gave me options to tinker with them, but nothing was changeable, including voltage and speed, which was still at 1600 rather than 1866, or it's max tested speed), but only one was being used. On Windows, It only found one RAM stick. Because of this happening, I decided to return my motherboard and replace it with a new one since it was already was having issues from the very beginning. After shipping in the new motherboard I tested the RAM again on a new one and it did not work. After testing the RAM stick separately they both worked. I believe the CPU might be the problem, but I can't be certain. I have not had enough time to run memtest on the computer because I have had very little time to return the defective product(s?). I do not have any spare room or CPU for testing. They came in a set and both of them are DIMM3s.
Checked the Gigabyte website and the RAM is compatible. Cpu-z found all 8 gigs but it was stuck on single channel mode. Help! (P.S I doubt it's the motherboard that is bad because I like I said, I tested it on a separate one and it still didn't work. Also, I tested both sticks in both sets of slots on both boards and the issue persists).

Motherboard: Gigabyte F2A88XM-D3H
CPU: AMD Athlon X4 860K (Black Edition)
RAM: G.Skill F3-14900CL9D-8GBSR
PSU: EVGA 500W 80 Plus
I'm running Windows 8.1 x64

I only have a day to fix this... ;-;
<I think it's the CPU.>

(((All parts are new)))

HELP!!!
 
Solution
As mentioned, either a CPU problem (most likely bent/broken pins), or a channel problem with the mobo, could be a scratched trace, debris in a socket, etc

I am using the stock cooler, and the sticks are currently in the 2 and 4 slots. Tested the 1 and 3 slots as well, same problem.

Only one of the ram sticks is activated when I have them both in 1 and 3 or 2 and 4. I made a mistake on my last post (It is now fixed). The ram sticks work fine separately in the 2 slot. I currently have them in 1 and 3 together and I have the issue. Putting them both in 2 or 4 has the same issue. The BIOS, however, would not post when one ram stick was in 4 or 3. It may be a cpu problem because it only doesn't post on 4 and 3 (The second set of ram slots the BIOS recognizes). Also, I forgot to say that the computer sometimes randomly freezes (normally for a second or two) on idle or web browsing, and completely freezes for around 3 MINUTES when opening Skype.
